commit bd22885aa188f135fd9 ("PCI: cadence: Refactor driver to use

and cdns_pcie_host_setup() but missed to remove the corresponding
pm_runtime_put_sync() in the error path. Fix it here.

Fixes: commit bd22885aa188f135fd9 ("PCI: cadence: Refactor driver to use

As this is a fix, a commit subject starting with PCI: cadence: Fix ... may
be more obvious.

I'd suggest you use the shorter form of this, i.e. Fixes: %h (\"%s\"))

Fixes: bd22885aa188 ("PCI: cadence: Refactor driver to use as a core library")

as a core library")

Okay.

There is probably more you can do here for both -host and -ep:

  - Remove the possibly now unused <linux/pm_runtime.h> include
  - Remove the err_init label and return directly from source.

Okay, will fix this up.

Thanks
Kishon
